Staphylococcus

Staphylococcus, from Ancient Greek σταφυλή (staphulḗ), meaning "bunch of grapes", and (kókkos), meaning "kernel" or "Kermes", is a genus of Gram-positive bacteria in the family Staphylococcaceae from the order Bacillales. Under the microscope, they appear spherical (cocci), and form in grape-like clusters. Staphylococcus species are facultative anaerobic organisms (capable of growth both aerobically and anaerobically).

Staphyloxanthin is a carotenoid pigment that is produced by some strains of Staphylococcus aureus, and is responsible for the characteristic golden color that gives S. aureus its species name. Staphyloxanthin also acts as a virulence factor. It has an antioxidant action that helps the microbe evade death by reactive oxygen species produced by the host immune system. left|thumb|250x250px|The pigment staphyloxanthin gave the bacteria [[Staphylococcus aureus a yellow color.]] When comparing a normal strain of S. aureus with a strain modified to lack staphyloxanthin, the wildtype pigmented strain
